Joe has freckles but Sue does not. Both have attached earlobes. Some of their children do not have freckles. Freckles and earlobes are inherited independently.
What is Joe's genotype?
What is Sue's genotype?
What is the chance that their next child will have both freckles and attached earlobes?
Could any of their children have unattached earlobes?
Please Include the Punnett Square.
Without knowing which traits are dominant or recessive, it impossible to answer these questions.
Use the information that I have posted to your other question to figure out the genotypes for each person for each trait, then combine the genotypes to do the Punnett square.
I hope this helps. Thanks for asking.
